摘要： An electrostatic latent image developing apparatus has a magnet housed in a developing sleeve and having at least one magnetized portion including adjacent poles of the same polarity. At least one of the poles of the magnetized portion is opposed to the casing of the developing apparatus, between the position where the developing sleeve is opposed to an electrostatic latent image bearing member and the position where the sleeve is opposed to a developer agitating roller. The other pole adjacent to and having the same polarity as this pole is positioned downstream from the pole with respect to the direction of rotation of the sleeve. Consequently, the upstream pole of the magnetized portion acts to retain a portion of developer between the developing sleeve and the casing, whereby the toner is prevented from spilling over the casing.

摘要： A copying machine of the present invention measures light transmittance of a document so as to adjust copying concentration on the basis of the measured result. The copying concentration is concretely adjusted by adjusting electrification voltage of a photosensitive body, and/or developing bias voltage, and/or quantity of exposure light. The copying machine is free from the occurrence of back image copying when a document is double-faced. A copying machine of the present invention further comprises means for discriminating whether the document is a double-faced one or a single-faced one.

摘要： The purpose of the present invention is to provide a conductive contact material, the contents of which do not generate soil on a charged body not only during initial use but also after repeated use. A conductive contact material consists of thermoset urethane material containing an antioxidant within a range from 0.1 to 0.3% by weight, and an inorganic ion electrically conducting agent with in a range form 0.01 to 2.00% by weight. After ozone exposure or the like, molecule chain scission of the base material and antioxidant leads generation of active monomers and origomers. However, the conductive contact material containing the above specified proportion of an antioxidant and an inorganic ion electrically conducting agent prevents generation of active monomers and origomers which are soiling source for a charged body. The conductive contact material also prevents antioxidant itself from being a soiling source. The employment of conductive contact material on a contact type charging device such as a transfer roller avoids disadvantages such as image noise caused by soil on a charged body without involving a large image forming apparatus and complex manufacturing process.
摘要翻译：本发明的目的是提供一种导电接触材料，其内容物不仅在初始使用时而且在重复使用之后不会在带电体上产生污垢。导电接触材料由含有0.1至0.3重量％范围内的抗氧化剂的热固性聚氨酯材料和0.01至2.00重量％范围内的无机离子导电剂组成。在臭氧暴露等之后，基材和抗氧化剂的分子链断裂导致活性单体和起始物的产生。然而，含有上述指定比例的抗氧化剂和无机离子导电剂的导电接触材料防止产生作为带电体污染源的活性单体和起源物。导电接触材料还防止抗氧化剂本身成为污染源。在诸如转印辊之类的接触式充电装置上使用导电接触材料避免了诸如图像噪声等引起的图像噪声，而不涉及大的图像形成装置和复杂的制造工艺。

摘要： Image density is detected by a B/W ratio detection integrator 30 via a video signal 11 from a video controller 40 when an image signal is inputted. When a latent image formed on a photosensitive body 7 in accordance with the image signal is transferred to a transfer material 12 by a transfer charging device 8, a transfer current of the transfer charging device 8 is controlled in a timely fashion by a CPU 20 in accordance with the image density detected from this image signal, thus ensuring optimum transfer efficiency. Even when the environment and printing pattern change for each part of a single-page image, this makes it possible to deal accurately with these changes to ensure stable transfer efficiency and good imaging.

摘要： This invention relates to the charging member portion of an image forming apparatus. A plurality of charging members are disclosed that maintain a uniform spacing between a charge-receiving member and the discharging portion of the charging members' electrodes despite surface irregularities and surface waviness on the charge-receiving member. One charging member is in the form of a flexible sheet provided with ventilation holes in a non-contacting portion thereof, permitting the air produced by the rotation of the charge-receiving member to escape through the holes to suppress the lifting of the charging member. Pressure fins can be added to the charging member on the downstream of the ventilation holes for further suppressing any lifting. Another charging member includes a semiconductive member or a electret member on at least the surface of the charging member on the side opposite the charge-receiving member. This permits the charging member to be electrostatically attracted to the charge-receiving member.
